CROWN, short for China Research and Development environment Over
Wide-area Network, is a grid testbed to facilitate scientific activities in different
disciplines. As we planned, the whole CROWN platform is consist of 3 parts. Firstly, many
resources (including computers, clusters and some storage devices) should be connected
via a nation-wide network infrastructure to build the CROWN architecture. Secondly, series
of grid middleware and auxiliary tools should be provided to meet the common requirements
of different scientific activities in all kinds of areas.Finally, a number of typical
applications should be put in use over the fabric and middleware to demonstrate the feasibility and robustness of CROWN.

DSSRetrieval
数字巡天图（DSS: Digital Sky Survey）由空间望远镜科研所（STScI）星表巡天部（Catalogs and Surveys Branch）制作提供。空间望远镜科研所为了获得设计导星星表所需要的图像数据，将施密特巡天底片数字化，覆盖了整个天空。通过网格服务的方式提供数字巡天图检索，初步实现一个虚拟天文望远镜的功能，通过输入区域参数，能够检索出相应区域的星空图。
Digital Sky Survey (DSS) is produced and provided by Catalogs and Surveys Branch of STScI (Space Telescope Science Institute). STScI digitized the Schmidt sky survey film which covers all the heaven, and the digital editions of these films have enormous practical efficiency on astronomical research. And the Grid Service of DSS supplies digital sky query, implements the function of a space telescope elementarily and virtually. DDS can find the corresponding region of the whole star graph by inputing the regional parameters.

AREM
Advanced Regional Eta-coordinate numerical prediction Model
中科院大气所LASG AREM（Advanced REM）是基于LASG REM（Regional Eta-coordinate numerical prediction Model）改进和发展的一个有限区域的数值预报模式。基于REM良好的动力框架， REM已初步发展升级为一个具有较先进科技水平的暴雨数值预报模式（AREM）。
Advanced Regional Eta-coordinate numerical prediction Model (AREM) of State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics (LASG) is an improvement and development of LASG Regional Eta-coordinate numerical prediction Model (REM). REM has upgraded and promoted to be regional eta-coordinate numerical prediction model on an much more advanced science and technology level elementarily, based on the favorable dynamic architecture of REM。

UDMGrid
University Digital Museum Powered by CROWN!
分布在CERNET不同服务器上的大学数字博物馆目前通过页面链接来简单互连，存在信息冗余、存储资源浪费、信息“孤岛”的现象，对于大学数字博物馆的不同知识层次访问者，只能提供的信息渠道和信息服务。UDMGrid的目标是利用网格技术整合18家大学数字博物馆的资源，实现更高层次的信息服务。
University Digital Museums distributed in different servers are connected with each other simply by hyperlinks among pages, therefore the disadvantaged phenomena exists such as information redundancy, waste of storage resources, and information "isolated island", Further more, single information access and information service are provided with to different academic classes of visitors or browsers. In order to implement advanced information services, the UDMGrid Applications will integrate the whole resources of 18 university digital museums via grid computing technology.

Clustalw
a general purpose multiple sequence alignment program for DNA or proteins.
一个基因多序列比对程序。CLUSTALW是一种渐进的比对方法，程序可以自由使用，对输入序列的格式比较灵活，用CLUSTALW得到的多序列比对结果中，所有序列排列在一起，并以特定的符号代表各个位点上残基的保守性，“*”号表示保守性极高的残基位点；“.”号代表保守性略低的残基位点。
